Gaseous Reduction Behavior of Powdered Iron Ore Sinter and Analysis on the Basis of Rist Model for Fixed Bed.

“…From the assumption that the equilibrium is attained at the interfaces, the oxidized ratios of hydrogen, P H 2 O /(P H 2 ϩP H 2 O ), at these interfaces can be calculated from the equilibrium constants for the hydrogen reductions. In these calculations, the following equations derived 12,13) on the basis of the data in the literature [14][15][16] are used: The calculated oxidized ratios of hydrogen, x 1 , x 2 , and x 3 , are shown on the left side of the corresponding interfaces in Fig. 1(a).…”
